This invention relates to the control of microorganisms such as fungi and the like. More particularly, the invention pertains to the control of fungi by means of systematically working fungicidal compositions containing as their 3,592,805 Patented July 13, 1971 active component a complex of an organic amine with a completely halogenated acetone.

In accordance with the present invention, it has been discovered that certain completely halogenated acetones having at least two fluorine atoms per methyl group and in which the two remaining halogens are fluorine or chlorine are capable of forming chemical complexes with relatively basic organic amines thereby engendering a family of chemical adducts which have proved to be unusually potent as systemic fungicides, and the provision of such complexes and a method of preparing them constitutes the principal object of the present invention. It is also an important object of the invention to provide fungicidal compositions containing at least one of the aforesaid complexes. Other objects and purposes will become manifest subsequently.

The systemic fungicides of the present invention can be represented by the following general formula:

wherein R and R can be hydrogen, an alkyl radical of from 1 to 18 carbon atoms, an alkenyl radical of from 1 to 18 carbon atoms, an alkynyl radical of from 1 to 9 carbon atoms, a non-aromatic carbocyclic radical of from 5 to 6 carbon atoms, an aralkyl radical wherein the alkyl portion is a lower alkyl and the aryl portion is a phenyl or naphthyl radical, an aromatic hydrocarbon radical such as a phenyl or naphthyl radical, cyano, an amino radical which may be substituted by lower alkyl and aryl radicals having from 1 to 2 aromatic rings and a heterocyclic radical, and taken together R and R may form a heterocyclic ring system as exemplified by pyrrole, pyrrolidine, imidazole, imidazoline, imidazolidine, piperazine, morpholine, isoxazine, dioxazole, tetrazole, and the like, it being provided that the aforesaid radicals may have attached thereto such functional moieties as halogen, e.g. chlorine, bromine or fluorine, CN, SCN, COOR, 4O NR SO R, SOR, SO R, CONR CONHR, -OH, SHS, NR NHR, NH OR, CO, SR, OC(O)R, --CHO,

The reaction is conveniently carried out in the presence of a normally liquid organic solvent, and in this connection reference is made to the lower ketones as exemplified by acetone, methylethylketone, and the like, alkyl cyanides, e.g. acetonitrile, and saturated aliphatic and aromatic hydrocarbons as well as their normally liquid chlorinated derivatives such as methylene dichloride, carbon tetrachloride, chloroform, ethylene dichloride, chlorobenzene, m-dichlorobenzene, etc. With the more reactive amines, usually those of fairly high basicity, the reaction with the fiuoroacetone can be rather vigorous and commonly occurs spontaneously on bringing together the reactants, necessitating external cooling means. On the other hand, the less reactive amines may require external heating in order to complete formation of the complex.

It is to be understood that the term relatively basic amine refers to those organic amines which form stable salts with strong acids as exemplified by sulfuric acid, hydrochloric acid, hydrobromic acid, perchloric acid, and the like. By stable amine salts is mean those which can be isolated and are stable under normal or ambient conditions.

Although the amine-halogenated complexes of the invention exert an overall influence on the metabolism of a wide spectrum of plant life, they are particularly effective in controlling the growth of fungi and other similar types of microorganisms. In general, we have found that the parasitic undifferentiated microorganisms are to a considerable degree more susceptible to the toxicants than the highly organized members of the plant kingdom. The aforesaid property is especially useful where it is desired to protect a valuable food crop against infection from attacking plant parasites. For instance, the compounds can be safely applied to bean plants to protect them against rust and mildew.

As previously pointed out, the complexes of the invention are systemic fungicides and this unexpected finding greatly increases their usefulness and versatility. As those skilled in the art are aware, a systemic fungicide is taken up internally by the plant to which it is applied and lodges in the plant tissues while still retaining toxicological properties. Obviously, systemic toxicants are not subject to weathering since they are confined within the interstices of the plant tissues which are thus internally immunized against the attack of harmful microorganisms such as fungi, molds, rust and the like.

Preparations suitable for fungicidal applications may be prepared in the form of dusts or sprays. For instance, a dust is prepared by intimately blending the halogenated acetone-amine complex with a finely divided solid carrier of which talc, diatomaceous earth, pyrophyllite, hydrated silica, clay and bentonite are typical examples. The active component normally comprises about 1 to of the total mixture. Moreover, it is a common practice to ernploy wetting agents to facilitate dispersing the active material in the event the dusts are added to water. Typically, a wettable powder may comprise to 50% of the complex, to 75% of one of the aforementioned finely divided solids, and 1 to 5% of a wetting agent. The aforesaid mixtures can be further diluted if desired. Exemplary wetting agents are the sodium alkylbenzenesulfonates, sodium dodecyl sulfate, and the nonionic polyethers as exemplified by the a1kylphenoxypolyethoxyethanols. In use, the wettable powder is stirred up in water and the resultant liquid sprayed on plants for protection against fungus diseases. Another common procedure for incorporating the toxicants of the invention in a form suitable for application to plants consists of dissolving the toxicant in an organic solvent such as xylene, toluene, ethylenedichloride followed by emulsifying the resulting solution in water in the presence of a dispersing agent. The solvent solution can also be applied directly.

In carrying out systemic fungicidal tests, 60 ml. of a solution containing the compound undergoing evaluation was diluted until the concentration was parts per million and the resultant diluted solution then placed in small tubes. A pinto bean plant was inserted in each tube using a cotton plug to support the seedling and also to retard evaporation. After 48 hours, two plants were inoculated with bean rust. Comparison between the treated and untreated plants was then made and the results evaluated. In these tests, the compound of Example 11 gave 100% control at a concentration of 1 part per million which, it will be noted, was the lowest concentration tested. Manifestly, this compound exhibits an unusually high degree of activity as a systemic fungicidal agent.

For specific instructions and directions for preparing the aforementioned complexes, reference is now made to the following examples which are inserted only for the purpose of illustrating the invention. It will be appreciated by those skilled in the art to which the invention pertains that various modifications and ramifications can be effected without departing from the spirit and scope thereof.

EXAMPLE 1 20.0 g. of sym. dichlorotetrafluoroacetone was diluted with 50 ml. of methylenedichloride and to the resulting solution was added gradually 9.3 g. of aniline. An exothermic reaction ensued, the result of which was to cause refluxing of the reaction. Following the addition of the amine, the reaction mixture was distilled under reduced pressure in order to remove all volatile products. There was obtained 19.5 g. of a slightly yellow residual oil which gradually solidified on cooling. The crude product was triturated with about 30 ml. of hexane, from which was obtained 15 g. of a white solid melting at 38 C. Analytical data and molecular weight determination were in consonance with the above depicted structure.

EXAMPLE 2 The procedure of Example 1 was again carried out but using equal molar proportions of sym. dichlorotetrafiuoroacetone and m-aminophenol. In general, the results were in consonance with those of the first example. After purification by crystallization from ether, there was obtained a light tan solid, the chemical analysis of which corresponded to the above depicted structure. This is an example of a complex wherein the molar ratio of reactants is 1:1.

EXAMPLE 3 4.8 g. of di-n-butylamino propylamine was dissolved in acetone and to the resulting solution was added 11.0 g. of hexafluoroacetone. After the initially exothermic reaction had subsided, the reaction mixture was subjected to reduced pressure and the volatile components distilled off. The desired product was obtained in the form of a yellow, viscous, oily residue which solidified on standing to a light yellow solid. The yield of product was 13 g.; M.P. 124126 C.

EXAMPLE 4 OOlFa CFa Chloropentafluoroacetone was dissolved into a mixture consisting of 4.8 g. furfurylamine and 30 ml. of methylene chloride, the introduction being continued until 5.5 g. of the halogenated acetone had been absorbed. After removal of the volatile components from the reaction mixture, there was obtained 10.0 g. of a residual yellow oil having an N of 1.4418.

7.0 g. of sym. dichlorotetrafluoroacetone was slowly added to a mixture of 9.2 g. of sulfamethazine suspended in 20 ml. of acetonitrile. There resulted an exothermic reaction with concomitant dissolution of the amine adduct. After the reaction was completed, as indicated by the falling temperature, the product precipitated as a voluminous, light yellow solid. The product was isolated by filtration and after drying amounted to 14.0 g. and decomposed at 120125 C.

EXAMPLE 6 4.8 g. of 2-amino-4-picoline was suspended in 40 ml. of methylene chloride and to the resulting mixture was added 10.0 g. of sym. dichlorotetrafiuoroacetone. After the addition, the picoline underwent dissolution and after removal of the volatile components by distillation, there was obtained 14.7 g. of a white solid which melted at 117 C.

EXAMPLE 7 4.1 g. of Z-methyl imidazole was suspended in 30 ml. of methylene dichloride to which was added 10.0 of sym. dichlorotertafiuoroacetone. There occurred immediately a rather mild exothermic reaction followed by simultaneous separation of the addition product. Isolation was effected by filtering off the white solid; its M.P. was 96-100 C.

EXAMPLE 8 coir o -NH-CN com 3.25 g. (0.025 M) diethylaminopropylamine was mixed with 20 ml. of methylene dichloride. To this solution was added 5.0 g. (0.025 M) of sym. dichlorotetrafluoroacetone. After the initially mild exothermic reaction had subsided, the mixture was allowed to cool to room temperature followed by the addition of 20 ml. of acetone and 4.1 g. (0.025 M) of hexafluoroacetone. The tem- 8 perature of the reaction rose to about 40 C. and then the above depicted structure and it is an example of an gradually dropped back to room temperature.
